python - Azure 函数要求 pdftotext

Question

我的 Azure 函数遇到运行时错误:

Result: Failure Exception: Exception: pdftotext is not installed. It is part of xpdf or poppler-utils software suite. 
Installation on Linux: wget --no-check-certificate https://dl.xpdfreader.com/xpdf-tools-linux-4.02.tar.gz && tar -xvf xpdf-tools-linux-4.02.tar.gz && sudo cp xpdf-tools-linux-4.02/bin64/pdftotext /usr/local/bin

由于我在本地安装了 xpdf，因此该函数在我的计算机上成功运行。我的问题是如何将pdftotext安装到我的函数的运行环境(linux)？
